          information;

     B.   During the Initial Term and any subsequent Term, and after termination
          of this Agreement for any reason (with or without cause), Kingsley
          agrees to forever hold in confidence and not at any time, in any way,
          directly or indirectly, to use for his own benefit or the benefit of
          some other person, firm, corporation or other entity, or to divulge,
          disclose or communicate to any person, firm, corporation or other
          entity, any confidential information unless (1) at that time the
          information has become, without any action by Kingsley in breach of
          this Agreement, generally and lawfully known to the public or in

          period from the date of termination of this Agreement for any reason,
          Kingsley shall not actively solicit or assist in the active
          solicitation of any employee away from ComEd's employ or to in any way
          impede the faithful discharge of such ComEd's agent's or employee's
          contractual and fiduciary obligations to serve ComEd's interests with
          undivided loyalty.

10.  OWNERSHIP OF INVENTIONS AND BUSINESS IDEAS
     ------------------------------------------
